How To Tell If A Stone is A Real Diamond: When purchasing what is purported to be a real diamond from a mall jewelry store or department store, there are some very basic methods that you can use to determine if the stone you are about to purchase is a real diamond or not. Step 1: Look through the diamond to see if you can see anything on the other side. Real diamonds refract a lot of light, so you cannot see any line circles or letters when looking through them. Step 2. If the stone is mounted, look through the top of the diamond to see if you can see the bottom of the mount. If by looking though the stone you can see the bottom of the mount, it is not a diamond. Step 3. Breathe on the stone. If your breath has created a mist on the stone, it is not a diamond. Breathing on a diamond does not create any moisture. Step 4. Look at the stone to see if there are small bits of minerals in the stone. If the stone is perfectly clear, it is not a diamond. Step 5: Rub the purported diamond on a piece of glass. Because diamonds are harder than glass, if the stone scratches the glass, it is probably a diamond.
